Title:
JOINT STRUCTURE FOR HIGH-VOLTAGE CABLE
Document Type and Number:
WIPO Patent Application WO/2019/179318
Kind Code:
A1
Abstract:
Disclosed in the present invention is a joint structure for a high-voltage cable, comprising a cable core. An inner insulating layer, a shielding layer, and an outer insulating layer are wrapped on the cable core in sequence from inside to outside; one segment of the inner insulating layer and of the outer insulating layer is stripped from the end of the cable core; the length of the stripped segment of the outer insulating layer is greater than that of the inner insulating layer; an outer terminal is connected to the end of the cable core; a heat-shrink tubing is wrapped at the junction of the end of the cable core and the outer terminal and on an adjacent segment of the inner insulating layer; there is a gap between the end of the heat-shrink tubing and the outer insulating layer; copper foil is wrapped in the gap and on the shielding layer; the shielding layer is externally connected to a cable joint by means of the copper foil. The present invention improves the safety during the connection between the cable joint and a high-voltage cable, can prevent oversized diameter of the tail end of the high-voltage cable, and can also prevent the shielding layer from being scraped by the cable joint.
